Intro

Suneera Madhani built Stax from an idea her employer rejected into a $1B fintech unicorn processing over $25B in payments. In this interview, the Stax co-founder shares how she went from selling credit card terminals out of her car to pioneering the first subscription-based payment processor, raising over $500M in capital, and scaling a company now generating $120M+ in revenue. From turning down a $17.5M acquisition offer to building an omnichannel platform before “fintech” was even a word, Suneera breaks down the strategies, resilience, and leadership lessons that took her from a scrappy founder to one of the most successful female entrepreneurs in tech.
